It’s pretty funny to me that people prefer to listen to advertisements over experts.
Companies can put out any piece of written or video garbage plus people seem to lap it right up. If they do bother to check their facts, I feel like they would rather side with the company who had out to make a buck off of their purchases rather than listening to the people who have years of experience in the field. At least, that seems to be how it is with my family plus their seriously odd views about indoor air quality. Since this pandemic began, my family started going overboard with their indoor air quality problems. I understand why you would want to make sure that you were breathing high quality indoor air as much as possible, however there are particular things that aren’t going to make a big difference. But doesn’t stop my family from purchasing costly air filters, media media air cleaners, filling the ductworks with cleaning products, plus buying UV light disinfection methods. It’s the last two air scrubbing policies that genuinely don’t work. From my years working in a biological research lab, I can tell you that UV light is not the best way to disinfect your air. A brand new UV bulb can kill microscopic toxins, organisms, plus airborne contamination. There is no doubt about that. However, UV lights abruptly lose their powerful disinfection capabilities over time. Working in the lab, I had to observe the ventilation in controlled fume hoods. If my enjoyable friend and I had a UV light in use for air disinfection, the bulb had to be substituted every couple of months. I know for a fact that modern Heating plus Air Conditioning companies developing their media air cleaners with UV lights are not advertising this to their buyers. If they are, my family definitely is not listening.
